Wife turns on the "night light" on the microwave last night and everything was ok, she gets up this morning and there's no display or anything on the microwave. Where do I start?
There is power at the receptacle and it's plugged in.

Does the microwave work with that display off?

It does nothing when any button is pushed. It's like there's a blown fuse or something, but unless it's a fluke, something blew the fuse.

Check the fuse and cavity thermostats. There are three cavity thermostats. They can be reset but you need to freeze them to -35ēC. You could probably do it with an air duster turned upside down. Get one that has Trifluoroethane, which boils at -46ēC, Difluoroethane and Tetrafluoroethane aren't cold enough.


I don't know why they made them reset so cold, LG thermostats reset at 0ēC, so you can just throw them in a freezer for a few minutes.
